L1 Line Loss Trip
The E300 relay trips with a L1 Line Loss indication if:
• No trip currently exists
• L1 Over Current Trip is enabled
• L1 Line
Loss is activated via the appropriately programmed digital input
(see
Input Assignments, Parameters 196…201, in Chapter
4)
• Line Loss Inhibit Timer has expired
• L1 Percent FLA (Parameter 47) is
• equal to 0% for a time period greater than the L1 Line Loss Trip Delay.
If
the E300 relay trips on a L1 Line Loss, the:
• T
RIP/WARN LED status indicator flashes a red 14-short blink pattern
• Bit 13 in Current Trip Status (Parameter 4) sets to 1
• Bit 0 in Device Status 0 (Parameter 20) sets to 1
• Any relay outputs configured as a Trip Relay open
• Any relay outputs configured as a Control Relay open
• Any relay outputs configured as a Trip Alarm close
• Any relay outputs configured as a Normal Relay are placed in their
